Experimental Study on Structural Performance of Precast Reinforced Concrete Core Wall under Action of Low Axial Load
No full textIn the core wall system in high-rise buildings, the four L-shaped core walls at the center effectively reduce seismic vibration. On the other hand, precast core walls are effective for construction because they can be built more quickly than cast-in-place core walls. In this study, a lateral loading test was conducted on a wall column simulating the corner and the area near the corner of an L-shaped core wall under the action of low axial load. The wall column was divided into precast columns, and horizontal tied rebars were concentrated at the second and third floor levels, and the mid height level of the first story. Based on the results of lateral loading tests, the structural performance of the wall column under the action of low axial loadwas clarified
Morphological Characteristics of the Lateral Abdominal Muscles in Athletes
No full textThe purpose of this study was to elucidate the morphological characteristics of the lateral abdominal muscles of university athletes who participate in competitions that involve frequent torsional motion. The subjects were 16 male university athletes (athletic group; five from the baseball club, three from the canoe club, and eight from the tennis club) and 19ordinary university students (non-athletic group). The lateral abdominal muscles (external oblique muscle, internal oblique muscle, and transverse muscle) were measured for muscle thickness using B-mode ultrasonography. Comparison of the athletic and non-athletic groups revealed a significant difference in the external and internal oblique muscles, both of which were thicker in the athletic group compared to the non-athletic group. No significant difference was seen in the transverse muscle. The calculated effect size was significantly larger in the internal oblique muscle compared to the external oblique muscle. Marked development of the abdominal oblique muscles, especially the internal oblique muscle, was found to be a morphological characteristic of the lateral abdominal muscles of athletes who participate in competitions that mainly involve torsional motion
The Relationship between Ability to Maintain a Stable Posture on an Unstable Stool and Area of Center of Gravity Displacement in Male University Soccer Player
No full textVarious tests have been developed to assess the ability to balance. The area of the center of gravity displacement test (voluntary stimulation test: VS test) assesses balancing ability when a person is subjected to added physical stimulation to make the body unstable. On the contrary, the test related to maintaining a stable posture on an unstable stool (involuntary stimulation test: IS test) assesses the balancing ability when a person is subjected to added physical stimulation while continuously standing. This study aimed to examine the relationship between each of these tests and balancing ability. The subjects were 16 male competitive soccer players (mean age, 19.3 years; SD, 1.2 years). The outline area for the VS test and the stable index for the IS test were selected as evaluation parameters. The relationship between these parameters was examined by Pearson correlation coefficient. The significance level in this study was set at p < 0.05. No significant correlation was attained between these two parameters (r = 0.04, p > 0.05). To conclude, the IS test is related to a different functional ability than the VS test
Rain Stock – Urban Development for Keeping Rainwater – Movie Created to Explain the Word "Rain Stock"
No full textA movie has been created to explain the word “rain stock,” which is technically “rainwater harvesting,” according to the Architectural Institute of Japan Environmental Standards. The movie, titled “Rain Stock - Urban Development for Keeping Rainwater,” is available on YouTube. Creation of the movie started in December 2015 after stages of technical advice by the Sub Committee for Promotion of Rainwater Harvesting, Architectural Institute of Japan. The movie was uploaded to YouTube in June 2016.We managed the creative process from the storyboard illustration and narration recording to the launch of an open YouTube channel with an English subtitled version in January 2017 to attract more viewers
Voice Communication System Using the Wire less Etherphone
No full textIn this article, we propose a disaster communication system using ad-hoc mesh network. In this system, we use the Etherphone which is communication technology using only the data link layer and the physical layer of OSI reference model. In previous research it was shown that the wireless Etharphone can perform ad-hoc communication. However, it is not shown that voice communication can be performed with the wireless Etherphone. It shows that voice communication is possible with the wireless Etherphone
Increased Speed and Performance of Protein Staining with SYPRO® Ruby Protein Gel Stain using Hot Water Incubation
No full textThe author presents a novel rapid, low-cost staining protocol (hot water protocol) for proteins
in a polyacrylamide gel using the fluorescent dye SYPRO® Ruby. Compared to the supplierrecommended
protocol, the hot water protocol showed equivalent dynamic range and linearity, and
a lower detection limit. Peptides prepared with in-gel digestion extracted from polyacrylamide gels
stained using the hot water protocol showed a sequence coverage ratio equivalent to that obtained
using the supplier-recommended protocol, and de novo sequencing could also be carried out without
issue. In addition, use of the hot water protocol dramatically decreased speckling noises owing to
prolonged staining time or storage of the dye solution. These results demonstrate the superiority of
the hot water protocol over the supplier-recommended protocol
